ash: undo "tokname hack"
dash has tokendlist[] array to decide which tokens end lists.
We store it as first byte of each tokname_array[i].
Switch to bit array, name it like dash (tokendlist), drop special
1st byte of tokname_array[i]. This brings us closer to dash, and
shrinks the binary, because many more string aliasing opportunities
are now open:
function old new delta
pstrcmp1 - 16 +16
readtoken1 2852 2858 +6
list 326 327 +1
pstrcmp 16 15 -1
tokname 45 42 -3
